Functionalized nanosilica is used to carry agrochemical IAA via disulfide bonds. • Under GSH environment, SiO 2 -S-S-IAA exhibits significant redox responsiveness. • The -SH on the surface of SiO 2 can form complexes with various heavy metal ions. • Dual-functional nanocarrier allows sustained IAA release and capture of metal ions. Owing to the low efficiency and lack of target specificity in the application of agrochemicals, e.g., plant growth regulators, the resulting environmental pollution and resource waste have raised enormous concerns over environments and human health. Herein, a redox-responsive nanosilica carrier (SiO 2 -S-S-IAA) was developed for efficient release of 3-indoleacetic acid (IAA), by functionalizing the surface of nanosilica with 3-mercaptopropyltrimethoxysilane (MPTMS), followed by the covalent coupling of IAA via redox-cleavable disulfide bonds. Under the high level of glutathione (GSH) in the plant microenvironment, IAA was released in a controlled way through disulfide bond cleavage, thus achieving redox response. In vitro controlled-release experiments confirmed that the release amount of IAA was significantly higher in the environment of 10 mM GSH, more than 10 folds at pH 5.5. Meanwhile, the thiol groups generated after release could form complexes with various heavy metal ions (Hg 2+ , As 3+ /As 5+ , Cd 2+ , Pb 2+ ), with the highest adsorption efficiency towards Hg 2 + up to 57.95%. More importantly, in planta experiments under cadmium stress have demonstrated that SiO 2 -S-S-IAA not only promoted rice seedling growth but also significantly reduced Cd 2+ accumulation in shoots, effectively inhibiting its transfer to edible parts. This work establishes a dual-functional nanocarrier platform that combines targeted agrochemical delivery with in situ heavy metal immobilization, offering a promising strategy for sustainable and precise crop protection.

In this study, a novel Z-type heterojunction photocatalyst ZnIn₂S₄/Cu 2 O was successfully constructed for the efficient degradation of tetracycline in aquatic environments. Flower-like ZnIn₂S₄ microspheres and cubic Cu 2 O were prepared via hydrothermal and water bath synthesis methods, respectively, and then composited through a solid-state pyrolysis-assisted ultrasonic dispersion method to form ZIC composites with different mass ratios (ZIC-2, ZIC-4, ZIC-6). Characterization results show that Cu 2 O nanoparticles are uniformly loaded onto the surface of ZnIn₂S₄ microspheres, forming a close heterojunction interface. Under visible light irradiation, ZIC-4 achieved a TC degradation efficiency of 91.2% within 60 min, significantly outperforming pristine ZnIn₂S₄ and Cu 2 O. Photoelectrochemical tests indicate that the Z-type heterojunction effectively promotes the separation and migration of photogenerated electron-hole pairs and suppresses charge carrier recombination. Radical trapping experiments and EPR tests confirm that superoxide radicals (·O₂ − ) and holes (h + ) are the main reactive species. The composite also exhibits good photostability and recyclability, providing a novel and efficient photocatalytic material for visible-light-driven removal of antibiotic pollutants from water.

Inspired by the natural synchronization of organic matrix
biosynthesis
and inorganic mineral deposition in coral reefs, this study introduces
a novel synchronous in situ biomineralization method. This strategy
aims to overcome the challenges of weak interfacial bonding and complex
processing in the fabrication of bacterial cellulose/calcium–phosphorus
composites (BC/Ca–P). Calcium gluconate was used as a dual-functional
precursor by substituting d -glucose in culture medium to
simultaneously supply a carbon source for BC biosynthesis and calcium
ions (Ca 2+ ) for mineralization at different substitution
ratios (10% for BC-CaG 10 and 100% for BC-CaG 100 ). We achieved concurrent biosynthesis of the BC matrix and deposition
of Ca–P phases, leading to a unique inorganic–organic
architecture in which Ca–P nanoparticles were uniformly anchored
within the BC nanofibrous network and strongly integrated by interfacial
interactions. Consequently, the moderate mineralization in BC-CaG 10 significantly enhanced the mechanical strength through a
synergistic reinforcement mechanism, reaching 12.03 MPa, representing
a 115% increase compared to that of pure BC. Conversely, the high
mineral content of BC-CaG 100 facilitated the formation
of a bioactive hydroxyapatite (HAP) phase, providing abundant active
sites. In preliminary biomedical evaluations, the fabricated composites
exhibited favorable biocompatibility. Notably, BC-CaG 100 exhibited efficient hemostatic performance in a rat tail amputation
model, reducing hemostasis time by 71% (to 142 s) and blood loss by
97% (to 15 mg). This study presents a facile, scalable, and green
approach for preparing novel biomimetic materials with promising potential
for biomedical applications, including tissue engineering and wound
management.

The development of metal-based membranes featuring hydrophilic
and oleophobic properties is essential for industrial oil–water
separation. Most industrial filters have a cylindrical shape to match
other filter components. The modification of the cylindrical surface
is much more difficult than the plane surface owing to the challenges
of reaction and mass transfer on the tubular surface. To address this
issue, we developed an electrochemical deposition method that enables
the direct construction of a hydrophilic and underwater oleophobic
coating on a cylindrical nickel foam substrate through precise mass
transfer control. By optimizing the mass transfer dynamics and employing
a stepwise deposition strategy, we achieved uniform functionalization
on an industrial-scale cylindrical membrane with a length of 25 cm.
The modified membrane exhibits an underwater–oil contact angle
exceeding 140 ° coupled with excellent durability, chemical stability,
and thermal resistance. Notably, it demonstrates high separation efficiency,
reducing the oil content in water from 1500 to below 200 ppm. This
work presents a scalable and reliable fabrication route for high-performance
cylindrical oil–water separation membranes with significant
industrial potential.

Innovatively developed an “adhesion-assisted growth” strategy for fabricating MOF membranes. • Constructed dual-confined ion channels enabling highly selective lithium-ion transport. • Implemented seed implantation in the adhesive layer to induce rapid and well-ordered MOF growth. • Established interconnected interface architecture forming continuous ion transport networks. • The developed membrane exhibits excellent long-term operational stability. Membranes featuring ordered biomimetic ion channels have been widely explored for ion-sieving applications, such as lithium extraction from salt-lake brines, seawater desalination, and energy conversion. However, achieving high ion permselectivity while enabling scalable fabrication for industrial use remains a major challenge. Here, we report a dual-confined metal-organic framework (MOF) membrane fabricated via an “adhesion-assisted growth” strategy. By integrating biomimetic ion channels functionalized with acidic groups, precise pore-size control, and surface chemical modulation, the membrane establishes a dual-nanoconfined separation system that simultaneously enables efficient Li + transport and effective Mg 2+ rejection. This specially designed adhesive layer not only promotes the well-defined formation of the MOF layer but also creates an interconnected ion transport network, thereby accelerating ion migration during selective electrodialysis (SED). Consequently, the resulting MOF membrane achieves a Li + flux of 1.17 mol·m −2 ·h −1 and exhibits a Li + /Mg 2+ permselectivity 14.3 times higher than that of the unmodified membrane, alongside excellent long-term operational stability. This environmentally friendly lithium extraction strategy advances the development of high-performance separation membranes and holds great promise for key applications such as lithium recovery from salt-lake brines, offering an innovative technological pathway toward efficient strategic resource recovery and the advancement of a circular economy. The synergistic dual-confined mechanism governs the selective Li + /Mg 2+ sieving performance of the MOF membrane. Download: Download high-res image (146KB) Download: Download full-size image

Conventional elastomer-based thermal interface materials (E-TIMs) are constrained by the trade-off between high thermal conductivity and low thermal contact resistance, limiting their use in high-power chip cooling. We developed a vitrimer-enabled, through-thickness vertically aligned graphene-fiber E-TIM that addresses this limitation by combining vertically continuous heat-conduction pathways with an adaptive polymer interface. Continuous graphene fibers were mechanically aligned, infiltrated with a β-hydroxy ester vitrimer-based polydimethylsiloxane matrix, and assembled through stacking-welding to form dense, continuous heat-transport pathways along the thickness direction. At a graphene-fiber volume fraction of only 16.71 vol %, the E-TIM achieves an ultrahigh through-plane thermal conductivity of 160.2 W m –1 K –1 , approaching the parallel-model estimate, indicating efficient translation of the axial thermal conductivity of GFs into macroscopic through-plane heat transport. Thermally activated transesterification in the vitrimer matrix enables stress relaxation, layer welding, and interfacial morphological reconstruction, reducing the thermal contact resistance to 14.4 mm 2 K W –1 under 40 psi. Molecular dynamics simulations further suggest that vitrimer-induced interfacial reconstruction increases the effective contact area and interfacial thermal conductance beyond conventional viscoelastic creep. In a device-level cooling demonstration, the E-TIM outperforms a commercial E-TIM by lowering the steady-state heat-source temperature by 20.8 ° C, highlighting its strong potential for high-power chip thermal management.

Evaluating endocrine-disrupting chemicals (EDCs) risk such as mono-butyl phthalate (MBP) and bisphenol A (BPA) raises a pressing question: can doses deemed safe for each individual exposure become hazardous in combination? This study aimed to determine whether environmentally relevant concentrations of MBP and BPA exert synergistic neurotoxicity and to elucidate the underlying molecular mechanisms using an integrated multi-omics approach. Exposure concentrations (20 nM each) were derived from epidemiological biomonitoring data. Primary neural stem cells (NSCs) were used to detect CCK-8, reactive oxygen species (ROS), and apoptosis Synergy was evaluated using the Bliss independence model and two-way ANOVA. Transcriptomic (RNA-seq) and untargeted metabolomic (LC–MS) profiling were performed, followed by integrative pathway analysis. Three-dimensional (3D) brain organoids were used to validate the main findings. Co-exposure to MBP and BPA at equimolar concentrations synergistically reduced cell proliferation (BlissΔ >0, E _Observed = 0.371 vs. E _Bliss = 0.163) and synergistically elevated intracellular ROS (interaction index = 2.21, p = 0.0066; two-way ANOVA interaction p = 0.033). Transcriptomic and metabolomic analyses converged on glutathione metabolism as the most significantly dysregulated pathway in the co-exposure group. Integrated multi-omics analysis revealed ferroptosis may serve as the primary mode of synergistic cell death. Three-dimensional brain organoids confirmed the ferroptosis signature, with significantly decreased GPX4 and SLC7A11 protein expression and concomitantly increased ACSL4 in the co-exposure group. In summary, MBP and BPA co-exposure at human-relevant doses synergistically induces neurotoxicity in NSCs through glutathione metabolism disruption and subsequent ferroptosis. These findings underscore the importance of evaluating chemical mixtures rather than individual compounds in neurodevelopmental risk assessment.

Ion
valence state analysis in aqueous solutions is of
critical
importance as the oxidation state of metal ions governs their chemical
reactivity, environmental behavior, and biological effects. Conventional
spectroscopic and electrochemical techniques are often limited by
low selectivity, poor applicability, complex and lengthy sample preparation,
or requiring bulky or expensive instrumentation. Here, we use the
functional relationship between triboelectric charge transfer and
trajectory position as triboelectric spectroscopy (TES), for the rapid
and efficient identification of metal ion valence states in aqueous
solution. By analyzing the peaks positions and corresponding magnitudes
of charge transfer in TES, we successfully identified 15 different
valence states across seven metal elements, achieving a detection
accuracy above 90% with detection limits down to the ppb level. Most
importantly, this work advances the fundamental understanding of liquid–solid
contact electrification by identifying key physicochemical factors
(ion valence and nanoparticle surface states) that govern the spatial
distribution of charge transfer, helping to address a key unresolved
scientific question─the origin of the non-uniform, peak-like
charge transfer distribution. The information derived from TES offers
a broadly applicable, ultrafast (<0.6 s), non-destructive, low-cost,
and portable analytical tool for assessing the oxidation states of
metal elements, including both ions and suspended nanoparticles in
liquid, demonstrating significant potential for analytical chemistry,
real-time environmental monitoring, and biomedical diagnostics.

Bt cotton outperforms non-Bt cotton in arsenic tolerance and root accumulation. • Bt cotton exhibits lower arsenic translocation and stronger antioxidant defense. • Arsenic stress slightly reduces Bt protein expression (≤19.5%) but remains within normal range. • Bt cotton may be suitable for arsenic-contaminated irrigation and phytoremediation. Irrigation with arsenic-containing groundwater threatens cotton production in Xinjiang, China, but whether transgenic Bt cotton has higher tolerance to arsenic stress than non-Bt cotton remains unknown. We compared Bt and non-Bt cotton under hydroponic As(V) stress (0–10 mg/L, 5 and 10 days). After 10 days at 10 mg/L, Bt cotton showed a significantly higher arsenic removal rate (68.76%) than non-Bt cotton (67.43%, P < 0.05). Arsenic mainly accumulated in roots. Bt cotton roots had significantly higher arsenic content (31.16–109.90 mg/kg) and bioconcentration factor (BCF) than non-Bt roots, while the translocation factor (TF) was significantly lower in Bt cotton (0.0759–0.0921 vs. 0.0931–0.1494, P < 0.05), indicating stronger root arsenic sequestration. A possible explanation is that As(V) may form a complex with the Bt protein, which could hinder arsenic translocation. Consistently, Bt cotton exhibited lower MDA content and higher activities of SOD, CAT, and POD than non-Bt cotton, demonstrating superior oxidative stress tolerance. Arsenic stress moderately reduced Bt protein expression (maximum decrease 19.47% at 10 mg/L after 10 days), but levels remained within the normal range. Bt cotton outperforms non-Bt cotton in arsenic tolerance and accumulation under hydroponic conditions, suggesting that it may be a suitable variety for planting in arsenic-contaminated irrigation regions and a potential phytoremediation candidate. Nevertheless, future field validation on arsenic-contaminated soils is essential to confirm the agronomic relevance of these hydroponic findings.

One-dimensional (1D) carbon fiber (CF) and two-dimensional (2D) MXene, with high strength and physical barrier properties separately, are expected to simultaneously realize a synergistic reinforcing effect as strengthening fillers in epoxy resin to protect steel structures. However, synergistic reinforcement is significantly limited by the chemical compatibility and dispersing state of fillers in resin due to the chemical inertness of CF and self-stacking properties of MXene. Inspired by the chemical structure of mussel’s foot filaments, Fe 3+ -tannic acid (Fe 3+ -TA) metal-phenolic networks (MPNs) were constructed on the surface of fillers. Herein, the 1D/2D CF/MXene synergistically reinforced coating was designed with enhanced performance by simultaneously incorporating TA/Fe 3+ @CF (TCF) and TA/Fe 3+ @MXene (TMX) into the epoxy matrix. In the coating, 1D TCF could resist impact, and 2D TMX could provide barrier properties. Erosion test results indicate the T(CF+MX)/EP showed a reduction in volume loss by 13.34% and 13.28%, as well as mass loss by 2.11% and 11.59%, respectively, compared to TCF/EP and TMX/EP. The | Z | 0.01Hz of T(CF+MX)/EP stayed at 1.15 × 10 9 Ω cm 2 even following 25 d of immersion under 60 MPa alternating hydrostatic pressure (higher than that of TCF/EP and TMX/EP). This study could provide insights for multiscale fillers design to utilize synergistic reinforcement with enhanced protective performance of coatings.

While
phenolic compounds are recognized as key atmospheric precursors
of brown carbon (BrC), the mechanisms governing their interfacial
transformation into BrC aerosols, particularly at the microdroplet
air–water interface (AWI), remain incompletely characterized.
This study investigated the photolysis of phenolic compounds in microdroplets
under UV irradiation, revealing a transformation efficiency 2 orders
of magnitude higher than that in bulk solutions. Through integrated
Fourier transform ion cyclotron resonance mass spectrometry, liquid
chromatography–mass spectrometry, and fluorescence excitation–emission
matrix spectrum, we identified interfacial-confined oligomerization
as the dominant pathway generating BrC with oligomer characteristics.
Multiscale theoretical simulations unveiled that the AWI functions
as a key mediator through a synergistic mechanism: it not only drives
the spontaneous accumulation of phenols at the interface, but also
enhances their photon absorption efficiency via asymmetric interfacial
H-π hydrogen bonding, as evidenced by a critical 24.7% increase
in the molar extinction coefficient at 298 nm. Together, these dual
effects synergistically facilitate photon capture and subsequent phenoxy
radical generation. Our results establish the AWI as photochemical
nanoreactors that fundamentally alter atmospheric BrC formation kinetics,
providing a mechanistic framework to reconcile field observations
of rapid aerosol aging under humid conditions, while challenging current
model assumptions about phenolic transformation time scales.

Owing to its low grade and complex dissemination, the efficient recovery of vanadium from stone coal vanadium ore remains highly challenging. To address this issue, this study proposes a novel approach, referred to as "narrow particle-fraction wüstite (Fe 1- x O) solid solution magnetization," which enables highly efficient vanadium enrichment from stone coal vanadium ore through the use of precisely controlled narrow particle-fraction Fe 1- x O. During roasting under a reducing atmosphere, vanadium-bearing components are thermally activated and diffuse into the Fe–O lattice of residual granular Fe 1- x O through the product layer, resulting in the formation of a ferrimagnetic Fe 3 O 4 –FeV 2 O 4 (Fe 3- x V x O 4 ) solid solution. Subsequently, the Fe 3- x V x O 4 phase is separated using low-intensity magnetic separation. Taken the stone coal vanadium ore with a V 2 O 5 content of 0.95 wt% as the raw material, under optimized Fe 1- x O particle size fractions and roasting parameters, the magnetic separation process yielded over 87% vanadium recovery in the concentrate, with a V 2 O 5 grade exceeding ten times that of the raw tailings, the processing volume required for the subsequent hydrometallurgical vanadium extraction process reduced by nearly 90%. Mechanistic analyses (SEM–EDS, EPMA, VSM, CLSM, and XRD) confirmed that the in situ-formed Fe 3- x V x O 4 solid solution served as an efficient magnetic carrier for vanadium in stone coal vanadium ore. Therefore, this approach provides a sustainable pathway for the efficient conversion of stone coal vanadium ore.
